Abstract (en)

[origin: EP0688710A1] Each bridge piece (4) of the concertina section has an elastically flexible profile (6) which at least partially overlaps the space between two bridge pieces and is clamped to the bridge piece. To stabilise the concertina section, each bridge piece has a housing (5) to which the profile is clamped. The elastic profile comprises a rectangular hollow body (6c) which extends laterally across approximately the halves of the space between two bridge pieces. <IMAGE>
